proto: Use SendmeTag in place of CircTag

2025-05-06T22:34:17Z

This doesn't make much change yet, but does save us an allocation when handling SENDMEs.

Add a RelayCellFormat argument to encode().

2025-04-16T14:58:49Z

This will let us actually _send_ messages in the right format. This approach is not ideal for packed/fragmented messages; they will need a separate RelayCellEncoder. part of #1944.

tor-proto: Use SENDME_TAG_LEN constant instead of magic value.

tor-proto: Use CircTag::try_from for clarity.

tor-proto: Use CircTag instead of raw byte slice.

proto: New CongestionControl object and fixed window algorithm

2025-01-16T14:16:01Z

Add the top level CongestionControl object that will allow the circuit reactor to use it in order to decide if a cell can be sent or not. In order to be used, it is configured with an algorithm that implements the CongestionControlAlgorithm trait. The Fixed Window algorithm is also added which essentially implements the SENDME logic as arti knows it today with a fixed window size. The SENDME code has been refactor in two different logical steps in order to accomodate the future Vegas algorithm for which the congestion window logic and SENDME validity is seperated. There is now a SENDME validator that takes care of tracking the tags (authenticated SENDMEs) and validating them upon reception. Then, if valid, the window management is passed down the congestion control algorithm, at this commit, FixedWindow object. Related #534 Signed-off-by: David Goulet
